Agency · Vendor-vetting · Company-buying
This is the agency-shopping path. If you are buying as a company — comparing fixed-price scopes against hourly-billed competitors, vetting vendors against a procurement checklist, asking for written summaries and a defects warranty — this is the right page. Productized scopes, senior engineers only, no retainers up front, 30-day defects warranty on every build. Engagement letter inside two business hours of the scoping call.
Short answer
If you are hiring an agency for base44 work, here is how Base44Devs works: fixed-price scopes published on the site, no hourly billing, senior engineers only with no junior bench, written summaries closing every engagement, and a 30-day defects warranty on every fixed-scope build. We only ship base44 — not Bubble, not Webflow, not FlutterFlow. Productized scopes run from $497 audits through $25,000+ enterprise migrations. Engagement letter inside two business hours of the scoping call. No account-manager relay layer: the engineer who scopes the work ships the work and signs the summary. Retainers are available after a successful first engagement, never sold up front. References available on request after a free 15-minute call.
What makes us different from a generic dev agency
The base44 agency SERP is dominated by generalist firms — Bacancy (1,000+ devs, 12 platforms, $22/hour), Concettolabs (16+ years, dozens of stacks), Nimap (3 continents, 328 employees). They are competent. They are also structurally wrong for most base44- specific work. Six differences a procurement team can verify before signing.
01
We do not ship Bubble. We do not ship Webflow. We do not ship Salesforce. Every engineering hour goes into base44 — every documented platform behaviour, every edge case in the AI agent, every change after a platform update is in our internal playbook before it hits your workspace.
02
Generalist agencies bill an account manager who relays your message to an engineer who relays an answer back. We skip the layer. The engineer who scopes the work ships it and answers your follow-up question 14 days later.
03
Every fixed-scope build carries a 30-day defects warranty. Any defect within the original scope reported inside 30 days post-ship is fixed at no cost. Written into the engagement letter, not negotiated separately. No agency we have benchmarked offers this.
04
If a $1,500 bug-fix sprint cannot resolve your issue — typically because the root cause is a platform-side bug we cannot work around — we deliver the diagnostic and refund the sprint fee. Distinct from the build warranty: this is on pre-build fix work.
05
Every audit, sprint, build, and migration closes with a written summary: changes, rationale, regression plan, follow-up watch items. So when base44 ships a breaking platform update six months later, you have a paper trail — not a Slack thread that nobody can find.
06
We are not a base44 reseller. We are not paid by base44. If the right answer for your business is a migration off the platform, that is what the audit will recommend. Most agencies that show up for "base44 agency" have an incentive to keep you on platform — we do not.
How we structure engagements
"Agency engagement" sounds vague because most agencies make it vague on purpose. Below are the three shapes our work actually takes. Each carries a written engagement letter inside two business hours of the scoping call, milestone billing, and the appropriate warranty or money-back clause.
Shape 01 · Single fix engagement
Most common. Buyer has one specific bug or production- readiness concern. Audit lands in one business day; sprint ships the fix in 48-72 hours. Total cost $1,997 (audit fee credited toward the sprint). Money-back if the sprint cannot resolve the issue.
Shape 02 · Build engagement
Buyer has a defined scope (MVP, internal tool, marketplace). Two-week to two-month engagement, weekly written progress notes, named engineer end-to-end, written hand-off doc, and 30-day defects warranty. No hourly billing, no scope creep.
Shape 03 · Retainer (post-engagement only)
For ongoing fixes, performance work, and platform-update coverage. Block model — you buy a defined number of senior engineering hours per month with rollover. Available only after a successful first engagement so we both know the fit. Detailed in expert services.

How to compare us against the alternatives
Vendor-vetting starts by mapping the obvious alternatives. Below is the quick comparison table. Detailed breakdowns live on the comparison cluster — each link below opens a 1,500-2,200 word page on the trade-offs.
| Generalist agency | Toptal | Upwork / Fiverr | Base44Devs | |
|---|---|---|---|---|
| Platform focus | 12+ platforms | Generalist seniority | Generalist, race to bottom | base44 only |
| Pricing | Hourly $22-$60/hr or vague | Hourly $80-$200/hr | Hourly $10-$80/hr | Fixed-scope, published |
| Engineer assignment | Account manager + bench | Single freelancer | Single profile | Named senior end-to-end |
| Subcontracting | Common, often hidden | Vetted but possible | Hidden offshoring common | Never undisclosed |
| Defects warranty / money-back | No | Limited replacement | No | 30 days on builds; money-back on sprints |
| Deliverable | Code + verbal hand-off | Code in repo | Code in workspace | Code + written summary + regression plan |

How it works
Most generalist agencies start with a two-week discovery phase before a line of code gets written. We compress that to three days for fix engagements and one week for builds. The pipeline below is what every client experiences.
Step 01
Confirm scope, urgency, and engagement tier. Disqualify ourselves if the work is a wrong fit.
Step 02
Written scope, named engineer, fixed price, deliverables, timeline. Inside two business hours.
Step 03
Read-only collaborator access. Reproduction inside the first hour. Written diagnostic report inside one business day.
Step 04
Fix shipped within 48-72 hours. Daily status updates. Written hand-off doc with regression watch items.
Reference engagements
Names redacted at client request. Pattern, scope, and outcome shared with permission. Reference calls available on request at engagement-letter stage for deals over $10,000.
Case 01 · Series-A SaaS
Series-A SaaS closing a $4M round had seven critical issues surfaced in investor due diligence. Audit identified all seven; multi-bug rescue resolved six in a 1.5-week engagement with the seventh deferred as a platform-side bug. Total spend $3,497. Round closed on schedule.
Case 02 · Marketplace at scale
Marketplace at 50,000 active users hit base44 platform limits on credit burn and rate limiting. Migration-feasibility audit recommended a phased migration; six-week medium migration shipped on schedule with a written rollback playbook. Defects warranty zero claims to date.
Case 03 · Internal tool MVP
Mid-sized enterprise needed an internal-only ops dashboard with SSO and write-access to a Postgres source-of-truth. Two-week build, named senior end-to-end, written hand-off doc, 30-day warranty (one minor defect filed and fixed inside the window).
Case 04 · Acquisition due diligence
Strategic acquirer buying a base44-built business needed an independent technical-risk register. Eight hours at $300/h. Delivered platform-lock-in analysis, code maintainability review, security posture, and 36-month TCO projection. Deal proceeded with a price adjustment based on the report.
QUERIES
Technically yes — we are a small team of senior engineers shipping base44 work on fixed-scope. But we deliberately do not behave like a typical agency. No 1,000-developer bench, no offshore subcontracting, no hourly meter, no "account manager" layer between you and the engineer. The engineer who scopes the work ships the work and writes the engagement summary.
Bacancy and Concettolabs are competent generalist agencies that offer base44 alongside Bubble, Webflow, FlutterFlow, Salesforce, and a dozen other stacks. If your project mixes base44 with three other technologies, they are a reasonable choice. If your project is base44-specific — fixing, building, or migrating — a specialist team has more reps on the platform and ships faster.
Toptal carries vetted generalist seniority but base44 specialism is rare on the platform; Upwork and Fiverr carry low-cost generalists who learn the platform on your dime. Base44Devs sits at fixed-scope productized senior specialism. Detailed breakdowns: /hire-a-base44-developer/vs-toptal, /vs-upwork, /vs-fiverr.
Fixed-price scopes wherever the work is well-defined. $497 audits, $1,500 sprints, $3,000 multi-bug rescues, $4,500-$15,000 builds, $6,000-$25,000+ migrations. We publish prices because hourly billing creates the wrong incentives. Builds carry a 30-day defects warranty: any defect in the original scope reported inside 30 days post-ship is fixed at no cost.
Yes, after a successful first engagement — but it is not how we lead. We are explicit about "no retainers up front" in the engagement letter because the right answer for most teams is a fixed-scope sprint or build, not an open-ended monthly contract. Retainers are typically $4,000-$8,000/month, available only after the fit is proven.
No. Every engineer on your engagement is named, bylined, and visible in the engagement letter. We do not subcontract to undisclosed offshore teams. If we ever bring in a specialist for a niche task, we name them in writing first and the buyer signs off before the engagement letter is amended.
A free 15-minute call to confirm scope, then either a $497 audit (for fix/migration work) or a paid scoping engagement (for builds over $9,000). Audit reports and scoping deliverables are credited toward the eventual engagement. Engagement letter inside two business hours. No surprise invoices.
Yes. Every fixed-scope build carries a 30-day defects warranty: any defect within the original scope reported inside 30 days post-ship is fixed at no additional cost. New scope or scope expansion is not covered (priced as a change order). The warranty is written into every build engagement letter, not negotiated separately.
